(c1. 15a-..991 1 ,The present invention relatesto improvements in lireI polishing` apparatus of the type, commonly employedv in the treatment; oi glass containers. In the production of glasscontainer's, the molding parts frequently produce finsv and likesharp edges or `rough projections-in proximity to the sealing surface withthe result that persons hars dling the articles` are likely'. to become injured thereby.

A leer conveyor i2,x is trained over rollers I3 at Vthe' outer' lvalve 29 is employed in controlling the flow of the combustible mixture of fuel and air to the burner units. Inasmuch fas the several burner` units are identical in construction and operation, the following detail description will be directed to one unit only.

and thereupon operated to shift the entire corresponding bracket 38 and parts carried thereby, longitudinally of the supporting rack bar 20. Thus the burners may be accurately aligned with the rows of articles to be treated.

In operation, bottles are placed in front of the extension l in a row extending transversely Each of these'units (Figs. l, 3 and 6) includes a vertical burner pipe 35 connected at ltsupper end through a union 36 to the aforementioned valve 29. A generally elongated burner .head,3 1

is attached to the lower end of the burner pipe 35, the latter being slidingly mounted in a bracket 38 which, as is shown in Fig. 6, includes a pair* of parallel horizontal arms 39 which are'spaced apart by a bearingV block 40. This bearing block (Figs. 4 and 6)M isfformed on the inner face of a yoke 4| which is intended to straddle one of the rack bars 20. .This yoke consists of a. pair'k of side walls 42 or plates and a spacer bar 43v aty and between the upperlend thereof,v all :of

of the leer and in proximity to the receiving end of the leer conveyor I2. At regular intervals a pusher bar 51 is operated to transfer a row of bottles to the leer conveyor. The conveyor then -moves the bottles lengthwise of the leer and in so doing, carries them beneath the group of burner units, the heads 31 of which are elongated in the direction of travel of the bottles to Vthereby. lengthen the period 0f fire polishing.

As stated heretofore, the burner units are ad- 'justable as to elevation and transverse spaced which are positioned at right angles tothe larms to adjustably control theielevation of the burner 31, includes a bell 'crank lever 44 mounted upon v a horizontal hinge'pin 45 at the outer'tend of the bracket 38, one arm 46 of said lever being i connected through a link 41 and a clamp 48 Vto burner pipe 35. The other arm 49 of this lever is suitably connected to an adjustable block 5|) which is threaded upon-the `inner end of an adjusting screw 5|. This adjusting screw is jour' naled in a'bearingblock 52 andan opening in the spacer 43 of said yoke 4| andl has its outer end'53 squared, or otherwise irregularly formed, for separable connection with' a wrench or other rotating means. By attaching a wrenchv or the burner units in a direction `transverse to the length of the leer in order that the burners may be axially aligned with the bottles, or other t Means for adjustingi the burner pipe and Y burners vertically in the bracketf38 whereby' Y cluding a frame, a burner unit including a verarticles, which are to bere polished. To this end IV have formed in each of the yokes 4| a horizontal opening 54 which is lso positioned with respect to the upper toothed edge of the corresponding rack bar' -that a pinion 55 carried by a hand crank 56 (Figzfl) may be inserted inthe openingand placed in mesh with the rack bar relationship in order to compensate for variations in the height and diameter of bottles or other articles being treated. Moreover, as is quite obvious, the burner units may be removed entirely.l for replacement simply by closing the main-'control valve 29', unscrewing the union coupling 36 and then lifting the yoke 4| and bracket 38 off of the supporting rack bar 26.

Modifications maybe resorted to within the spirit and scope of the appended claims.

l. Apparatusv ofthe character described intical burner pipe slidable through said frame, a burner headat the lowerend of the pipe, a horizontal bracket attached to one side of the frame, a bell crankl lever pivoted to said bracket, a link connecting one arm'of said lever and the burner pipe at a point below said `frame, an adjustable screw carried by the bracket, and operative connection between the screw and the other arm of said lever whereby rotation of the screw moves the lever about its pivot and eiiects Vertical adjustment of the burner pipe.

2. Apparatus of the character described including a frame, a burner unit including a vertical burner pipe slidable through said frame, a burner head at the lower end of the pipe, a horizontal bracket attached to one side of the frame, a bell crank lever pivoted to said bracket, a link connecting one arm of said lever and the burner pipe at a point below said frame, an adjustable screw carried by the bracket, and opern ative connection between the screw and the other arm of said lever whereby rotation of the screw moves the'lever about its pivot and effects vertical adjustmentof the burner pipe, said operative connection including a block threaded upon said screw and pin and slot connection between said block and arm.
